Fusinite Optimiser Landing
Which carbon standard pays most for your biochar?
The seven major biochar registries measure permanence in completely different ways. Run the same material through all of them and the credited tonnage can differ several times over — and some will credit nothing at all. The Fusinite Optimiser takes your laboratory chemistry and shows you, standard by standard, exactly what your biochar is worth.

The same biochar, seven different answers
Every standard sets its own permanence rules, its own thresholds and its own horizon. A batch that one registry rewards handsomely can fall the wrong side of another’s gate and earn nothing. Choosing well is worth real money, and choosing well requires knowing your chemistry.
Registry standards modelled, each ported from its own published methodology — not approximated by a single generic formula.
Laboratory measurements decide the outcome: organic carbon, H/Corg, inertinite fraction and mean reflectance. Temperature alone cannot tell you them.
What a single wrong choice of standard can cost. Several registries gate off entirely above a threshold, crediting nothing for material that others would pay for.
What you can do with it
Your chemistry comes straight from our laboratory and is read-only. What you control are the conditions — batch size, where the biochar is applied, the carbon price you have been quoted — and the portal restates every figure as you change them.
Overview
Your whole portfolio scored under all seven standards, ranked, with the leader named and the binding constraint on each one spelled out.
Scenario simulator
Change soil temperature, production temperature, dry matter or yield on any sample and watch the ranking re-order live, with a sweep showing where standards cross over.
Sample records
Every sample with its full measured chemistry, its result under each standard, and a clear mark on anything that was assumed rather than measured.
Registry detail
How one standard treats your biochar specifically — sample by sample, with the permanence factor it applies and why.
Biomass conversion
How much of a tonne of your feedstock ends up as permanently stored CO2, and how much biomass you would need to reach a target tonnage.
Revenue
What your portfolio is worth at any carbon price, and the spread between the best and worst paying standard — which is what choosing correctly is worth.
The seven standards
Each one is implemented from its own published methodology and verified against our reference workbook to the last decimal. None of them is an approximation of another.
What these figures are. The Optimiser reports gross model output for scenario planning. It makes no deduction for sample variance, uncertainty, buffer pools, reversal risk, leakage, lifecycle or project emissions, or any registry’s own deductions and eligibility rules.
They are not issued credits, not a certification, not a verification, and not financial advice. Fusinite is not a registry and not a Validation and Verification Body. Enrolment decisions need the full methodology of the standard concerned. Methodology versions checked 5 August 2026.
Modelling requires laboratory analysis of your biochar. Samples appear in the Optimiser once analysis is complete. Producers who have not sent us anything yet can still use the Range Finder, which estimates the spread between standards from your production temperature and carbon content — it reports a range, never a prediction.
